Question
Exam scenario ALC-bc00b5a5: Use error diagnosis to explain how the evidence supports the objective "Explain separation using stationary and mobile phases." in Chromatography (A-level only).
Answer
For ALC-bc00b5a5, a strong answer should use error diagnosis to address Chromatography (A-level only). It should identify the chemical principle in the objective "Explain separation using stationary and mobile phases.", apply the evidence from the prompt, and finish with a specific conclusion. This makes the question distinct from nearby items while preserving the same A-Level Chemistry curriculum coverage.

Common mistake
Confusing Phases
Students often confuse the roles of stationary and mobile phases in chromatography, thinking both are the same.
Remember that the stationary phase is the substance that does not move, while the mobile phase is the solvent that carries the mixture through the stationary phase.
